Overview

The ABB FSK 2 Aluminum Flood-Seal Compression Splice Kit is a precision-engineered solution for joining #2 STR CPT COMP AL-CU aluminum and copper conductors in industrial and utility applications. This kit includes a compression splice, FSS 20 cover and cap, silicone grease, and an instruction sheet, providing a complete, ready-to-install package. The aluminum construction ensures compatibility with both aluminum and copper conductors, reducing galvanic corrosion risks in mixed-metal installations. The flood-seal design creates a watertight, airtight connection, preventing moisture ingress and oxidation that can degrade electrical performance over time. The compression splice method delivers consistent, high-integrity joints with low contact resistance, minimizing heat generation and energy loss in high-current circuits. Typical applications include power distribution systems, substations, industrial motor controls, and renewable energy installations where reliable, long-term conductor connections are critical. The FSK 2 kit is optimized for #2 AWG stranded compact aluminum conductors, offering a secure fit and mechanical strength to withstand vibration and thermal cycling. Silicone grease included in the kit further enhances corrosion resistance and ensures stable electrical performance in harsh environments. ABB’s FSK series is trusted in utility and industrial sectors for its durability and compliance with industry standards for compression splices.
